    According to Canonical Correlation, the Evaluation of Bluefish (Pomatomus saltatrix) Blood Chemistry
    (Medwell Online, 2010) Bulut, Musa; Gultepe, Nejdet; Mendes, Mehmet; Guroy, Derya; Palaz, Mustafa
    Blood chemistry parameters can provide essential information on the physiological status of the animal and therefore allow accurate evaluations of the general health status. Canonical correlation analysis is a fundamental statistical tool. The goal of canonical correlation analysis is to evaluate the relative contribution of each variable to the derived canonical functions in order to explain nature of the relationships. CCA was used to determining, whether the blood protein parameters are related in any way to the blood lipids, enzymes, minerals. However, a linear association between predictor variables (blood proteins) and dependent variables (lipids, enzymes and minerals) were determining. These analyses results shown that canonical correlation analysis can be using prediction of relationships from blood proteins with other blood chemistry parameters.

    Culture of Fan Mussel (Pinna nobilis, Linnaeus 1758) in Relation to Size on Suspended Culture System in Izmir Bay, Aegean Sea, Turkey
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2011) Acarli, Sefa; Lok, Aynur; Yigitkurt, Selcuk; Palaz, Mustafa
    The growth and survival of fan mussel (Pinna nobilis, Linnaeus) juveniles, from natural spatfall, were compared in two groups (large and small size) in Karantina Island Izmir, Turkey, between December 2004 and April 2006. Total live weight, shell length, width and thickness of fan mussel were measured monthly during the study period. Small (32 mm) and large (73 mm) size groups of fan mussel individuals reached 140.25 +/- 10.46 mm and 154.36 +/- 16.12 mm in length and 64.64 +/- 17.98 g and 99.74 +/- 30.53 g in live weight, respectively. Significant differences were found in increases of shell length and live weight. Environmental parameters such as chlorophyll-a, seawater temperature, salinity, particulate organic matter (POM) and particulate inorganic matter (PIM) were determined during each sampling period. Shell length increase was affected by chlorophyll-a and PIM. However, increases in shell length did not correlate with temperature and POM. Survival rates for small and large groups were 93% and 100%, respectively.

    Distribution of macrozoobenthic invertebrates in the South Marmara Sea
    (2010) Palaz, Mustafa; Colakoglu, Serhat; Yildiz, Harun
    A study was undertaken between 2007-2009 in the Dardanelles. Monthly sampling was carried out in 4 stations up to 10m of water depths by using dredge. The samples were fixed and preserved in 5% formalin prepared in marine water. Morever, anatomical and morphological characteristics of identified species were illustrated with photographs. The specimens were examined the macroscopic and then microscopic under the light of binocular microscope. According to the results; total of 22 species belonging to 7 Order, 5 Kalssis was found in the South Marmara Sea. © Medwell Journals, 2010.

    POPULATION STRUCTURE AND DYNAMICS OF WARTY VENUS, VENUS VERRUCOSA (BIVALVIA, VENERIDAE), IN NORTH AEGEAN SEA, TURKEY
    (Natl Shellfisheries Assoc, 2015) Cxolakoglu, Serhat; Palaz, Mustafa
    The growth, reproduction, and density of warty venus clams (Venus verrucosa) were studied at a depth of 2-5 m in Baklaburnu Bay in the North Aegean Sea, Turkey. Samples were collected monthly between September 2012 and August 2013. The average density of the studied population ranged between 152 individuals m(-2) (October) and 310 individuals m(-2) (June). The shell length at first capture (L-50%) by hand rake was 37 mm. von Bertalanffy growth parameters using the length-frequency distribution of V. verrucosa were estimated at L-infinity = 57.65 mm, the rate at which the asymptotic length (L-infinity) is approached (K) = 0.25 y(-1), theoretical age (y) when the length = 0 (t(0)) = -0.211, and seasonal oscillation in the growth rate was 0.30. Growth was rapid during the first 4 y of life (similar to 40 mm) and decreased after the 4th y. The slowest growth period was in January (winter point = 0.03). Overall growth performance, growth performance index, and potential longevity derived from seasonal parameters were calculated as 4.68, 2.92, and 12.0 y, respectively. The growth pattern showed isometric growth (slope [b] = 3.09) and the spawning period occurred from mid-June to August.

    Some population parameters of Ruditapes philippinarum (Bivalvia, Veneridae) on the southern coast of the Marmara Sea, Turkey
    (BMC, 2014) Colakoglu, Serhat; Palaz, Mustafa
    Ruditapes philippinarum, a venerid clam, is a dominant species in the sandy and muddy areas in the coastal waters of the Marmara Sea. Intensive commercial harvesting of this species is conducted in these regions. We studied the population dynamics of R. philippinarum on the southern coast of the Marmara Sea (Bandirma). Samples were collected on a monthly basis between September 2012 and August 2013. Seasonal von Bertalanffy growth parameters using the length-frequency distribution of R. philippinarum were estimated at L-infinity = 67.50 mm and K = 0.33 year(-1), and the seasonal oscillation in growth rate was 0.53. The slowest growth period was in January. The growth performance index and potential lifespan were 3.182 and 8.06 years, respectively. The growth relationship was confirmed to have a positive allometric pattern. The average total mortality rate was estimated to be 0.777 year(-1), whereas the natural and fishing mortality rates were 0.539 and 0.238 year(-1), respectively. The current exploitation rate of R. philippinarum was 0.306. The recruitment pattern peaked during June-August, and spawning occurred between May and August. The results of this study provide valuable information on the status of R. philippinarum stocks.

    Temporary Timing of Reproductive Traits with Respect to Environmental Variables in Turkish Crayfish in Yenice Reservoir
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2011) Berber, Selcuk; Yildiz, Harun; Ozen, Ozcan; Mendes, Mehmet; Palaz, Mustafa
    This study was carried out to determine the relationships between physicochemical parameters and morphometric and reproduction features of the crayfishes (Astacus leptodactylus) in Yenice Central Irrigation Pond. Results of MDS analysis revealed that the relationships between physicochemical parameters and morphometric features and reproduction features in crayfishes could be explained at different rates. Reproduction features such as fecundity and sperm production, were within a close relationship with temperature, magnesium, conductivity, dissolved oxygen, and the abdomen weight, carapace weight, abdominal width, carapace width, abdomen length, carapace length from morphometric features were within a close relationship especially with dissolved oxygen, magnesium, calcium, and temperature. These relationships could play an important role while considering the selection of maternal females for cultural environments and for the management of productive population, and for the selection of water sources that can be effective for populations that is generated by vaccination.
